Dynamo DB to Postgres Heroku integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between Dynamo DB and Postgres Heroku: authenticate both systems, choose the objects to sync (such as Dynamo DB's Global Secondary Indexes and DynamoDB Streams), map fields visually, and changes propagate both ways in milliseconds — no code required.

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Common patterns for Dynamo DB and Postgres Heroku: Migration with zero-downtime cutover; Shared reference data between services; Regional or environment copies. When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

Dynamo DB: Proprietary JSON-over-HTTPS API accessed through AWS SDKs; PartiQL supported for SQL-like queries. Authentication: AWS IAM credentials with SigV4 request signing. Postgres Heroku: SQL wire protocol (standard PostgreSQL). Authentication: Database credentials from the Heroku DATABASE_URL config var; SSL required. Stacksync manages authentication, retries, and rate limits on both sides.

Dynamo DB: Items are schemaless apart from the mandatory partition key (and optional sort key), so sync field mappings are defined per attribute rather than from a fixed schema. Postgres Heroku: All connections require SSL, and server-level settings such as replication configuration are controlled by Heroku rather than the user. Stacksync's field mapping accounts for these differences between Dynamo DB and Postgres Heroku without custom code.

Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Dynamo DB and Postgres Heroku records are not retained after a sync operation.
